During the course of an analysis for a solid sample, a loss of 0.40 mg occurs. Calculate the percentage (%) of relative error due to weight loss inherent in the method. A. When the method is performed on a sample with a total weight of 4.0 mg. B. When the method is performed on a sample with a total weight of 400.0 mg. C. Briefly, discuss what would be the most appropriate sample size ((a) or (b)) for the analysis assuming that weight loss is inherent in the method and is not due to gross error.

Give the advantages and disadvantages of sequential injection analyzers compared to traditional flow Injection analyzers.
One method for quantitative determination of the concentration of constituents in a sample analyzed by gas chromatography is the area normalization method. In this method, complete elution of all of the sample constituents is necessary. The area of each peak is then measured and corrected for differences in detector response to the different eluates. This correction is accomplished by dividing the area by an empirically determined correction factor. The concentration of the analyte is found from the ratio of its corrected area to the total corrected area of all peaks. For a chromatogram containing three peaks, the relative areas were found to be 16.4, 45.2, and 30.2 in the order of increasing retention time. Calculate the percentage of each compound if the relative detector responses were 0.60, 0.78, and 0.88, respectively

Often the analyst will compare known quantities of analyte to unknown quantities of the material to be analyzed. This may be done in one of three ways: -use calibration curves; use standard additions; or use internal standards. The method of standard additions would be used when A) the quantity of sample analyzed or the instrument response varies from run to run. B) the standard solutions and the unknown solution all have similar characteristics are unaffected by the other material in the sample. C) the sample composition is unknown or complex and affects the analytical signal.
a sample of butyl benzoate is prepared to use as an internal standard. The results of a preliminary run, which used a solution known to contain 1.53 mg/mL of methyl benzoate (peak A) and1.68 mg/mL of butyl benzoate (peak B), are shown. The area of peak A is determined to be 352 and the area of peak B is determined to be 416 measured in arbitrary units by the computer. To measure the sample, 1.00 mL of a standard sample of butyl benzoate containing 2.19 mg/mL is mixed with 1.00 mL of the plant stream material. Analysis of the mixture gave a peak area of 449 for peak A and 411 for peak B. What is the concentration of methyl benzoate in the plant stream? concentration of methyl benzoate = ____________________ mg/mL

In analytical chemistry, when and why do we do representative sampling? How can you apply this concept in medical laboratory science? *
An internal standard is incorporated into an analysis method when systematic sources of variation (i.e., variation not under statistical control) exist that cannot be eliminated. A sample must be injected into the chromatographic system in order for it to be analyzed using HPLC. Which type of injection mode would create the largest source of systematic variation? automated sample injector manual sample injector
